⚡ KEY FEATURES

⏪ 10-Minute Instant Replay
Replay recently received transmissions if you miss them the first time.

📻 5 Watt UHF CB Output
Nominal 5 Watt transmit power across the Australian 80-channel UHF CB system.

📏 Compact Rugged Design
40 × 139 × 123mm transceiver designed for off-road, tradie and industrial applications.

🎙️ Heavy-Duty Microphone Plug
Designed to provide a solid connection in high-vibration environments.

⭐ 3 Instant Recall Channels
Quick access to three frequently used channels.

🔍 Open, Instant & Priority Scan
Multiple scanning modes for monitoring UHF CB activity.

📶 Duplex Repeater Capability
Supports compatible UHF CB repeater operation.

🔐 38 CTCSS Codes
Allows compatible radios to filter unwanted received audio.

🎛️ Rotary Volume & Squelch
Simple physical controls for quick audio adjustment.

🔊 External Speaker Jack
3.5mm connection for a compatible optional external speaker.

⏪ INSTANT REPLAY

The UHF048 can store up to 10 minutes of incoming audio for later playback.

This is particularly useful for convoy directions, road information, track instructions and worksite communications where a message may be missed because of traffic, cabin noise or concentration on driving.

⭐ 3 INSTANT RECALL CHANNELS

Three Instant Recall channels provide fast access to the frequencies you use most often, reducing the need to manually move through the full channel range.

🔍 SCANNING, DUPLEX & CTCSS

The UHF048 includes Open Scan, Instant Scan and Priority Scan, together with duplex operation for compatible UHF CB repeaters.

It also provides 38 CTCSS codes for compatible selective-squelch operation.

⚠️ CTCSS does not make communications private or encrypted.

⚠️ Duplex only provides a range advantage where a compatible repeater is available and within coverage.

❓ FREQUENTLY ASKED QUESTIONS

How much audio can the UHF048 replay?

Up to approximately 10 minutes of received audio can be stored for Instant Replay.

Is it a full 5 Watt UHF?

Yes. Nominal RF transmit output is specified at 5 Watts.

What are the three Instant Recall channels for?

They provide quick access to three frequently used channels without manually moving through the full channel range.

Can I use UHF CB repeaters?

Yes. Duplex repeater operation is supported using the standard +750kHz transmit offset.

Are CTCSS conversations private?

No. CTCSS filters received audio but does not encrypt the underlying UHF transmission.

Can I connect an external speaker?

Yes. The UHF048 provides a 3.5mm jack for a compatible optional speaker.

Can I install it directly into a 24V truck?

No. Its specified operating range is 10–15V DC, so a suitable 24V-to-12V conversion solution would be required.

Does an antenna come with it?

An antenna is not identified as included. A compatible 50-ohm UHF CB antenna system is required for operation.

How does the UHF048 compare with the UHF040?

The supplied specifications are extremely similar, including the same 5 Watt output, 10-minute Instant Replay, three Instant Recall channels, 38 CTCSS codes, 10–15V operating range and 40 × 139 × 123mm dimensions. There is not enough supplied information to claim a significant technical advantage for either model.

What should I check before buying?

Confirm your vehicle provides a compatible 10–15V DC supply, make sure the radio fits your intended mounting location and select a suitable 50-ohm UHF CB antenna.
